Guys, concerning the 100/133 jumper issue, I have done some tests together with the help from Iwill.
If you put in a chip designed for 100MHz (and not able to run at 133MHz), set the jumper to 133MHz, boot it up, it's gonna be disaster for sure.
But if you put the jumper in 100MHz position, boot up the chip at default multiplier, lower the multiplier, and make sure it boots at 100 x lowered multiplier, then shut down. Change the jumper to 133MHz position and boot up, it should work.
We together with the companies have tested two chips, a 800MHz (8x100) that can't do 1064 (8x133), and a 1000MHz (10x100) that can't do 1330 (10x133). Take the 800 as an example and the Iwill KK266 and the EPoX 8KTA3 as test bed.
With the jumper in the 133MHz position, we couldn't boot up the chip at all, simple coz' the chip couldn't stand the clock speed. We then put the jumper in the 100MHz position, and boot up at 800MHz no problem. We then lowered the multiplier to 6, and booted up the machine at 600MHz and entered Windows (just make sure it finished boot up). Then we shut down the system and change the jumper to 133MHz position. Boot up the machine, BIOS shows 800MHz (6x133) and entered Windows without a hitch. Continued to reboot and system and never had a problem as well.
We are not sure if that's the solution to all the cases yet, simple coz' we are dealing with a small number of chips and boards here, but using the above method we were able to deal with the problem (both AnandTech and Iwill).
We currently don't have the K7T Turbo so we couldn't do any further testing, but once we have the board back we will work on it.
if the above method is really the solution, things aren't that bad. Even if the above method turns out not working, the method discussed by DaddyG (Thanks DaddyG) should work flawlessly as well, except for 1.1GHz and 1.2GHz chips.
We will keep you guys posted on the issue.
